This gist lets you keep IPython notebooks in git repositories. It tells git to ignore prompt numbers and program outputs when checking that a file has changed.

To use the script, follow the instructions given in the script's docstring.

The procedure outlined here is inspired by this answer on Stack Overflow.

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

	all: test libtest.so testmodule

	libtest.so: libtest.c
	$(CC) -Wall -g -fPIC -shared -o $@ $? -lc

	test: test_main.c libtest.o
	$(CC) -o $@ $?

	testmodule: testmodule.c
	python setup.py build

	$: (Dollar Colon) is basically a shorthand version of $LOAD_PATH. $: contains an array of paths that your script will search through when using require.
	$0 (Dollar Zero) contains the name of the ruby program being run. This is typically the script name.
	$* (Dollar Splat) is basically shorthand for ARGV. $* contains the command line arguments that were passed to the script.
	$? (Dollar Question Mark) returns the exit status of the last child process to finish.
	$$ (Dollar Dollar) returns the process number of the program currently being ran.
	$~ (Dollar Tilde) contains the MatchData from the previous successful pattern match.
	$1, $2, $3, $4 etc represent the content of the previous successful pattern match.
	$& (Dollar Ampersand) contains the matched string from the previous successful pattern match.
	$+ (Dollar Plus) contains the last match from the previous successful pattern match.
	$` (Dollar Backtick) contains the string before the actual matched string of the previous successful pattern match.

	>>> import sys
	>>> import os
	>>> sys.executable
	'/usr/local/bin/python3'

	OR

	$ which python3
	/usr/local/bin/python3
